Accident Classified As: Reportable Quantity

Cause of Problem: Equipment Failure

K-406 unexpectedly shut down and waste gas was automatically diverted to refinery safety flare system.

Discharge Preventable - No

Notes/Remedial Actions

Sweet streams (lower Sulfur content) were routed to the flare to minimize sour gas flaring. Process unit output was adjusted in order to minimize the total amount of waste gas being sent to the flare. Shortly after shutdown, personnel re-started K-406 restoring the systems ability to process available refinery waste gas streams, ending the incident.
